Yea Chuck is just making silly talk about OKC and SA because it's entertaining to the big city viewers that are their main demographic. We have no reason to be offended by it. It's entertaining to me also.
I mean, really, if you haven't grown up in San Antonio, all you know about it is the Alamo and River Walk. It seems kinda boring, and there's nothing wrong with making a bit of fun over it. Having never been to New York and only once to LA, I can name dozens of fun tourist attractions, but most people can't think of more than 1 or 2 interesting things about OKC or San Antonio.
It's all in good fun no reason to be upset.
